Law Firm Matter Profitability Calculator (Free Tool)
Calculate the true profit margin on any matter using billable hours, realization rate, and loaded attorney cost.
Estimated matter profit margin
--Updates as you change inputs. Estimate only, not legal advice.
Most US law firms track revenue per matter, but very few track true profitability. This law firm matter profitability calculator estimates the net margin on a single matter by comparing collected revenue against attorney cost, realization rate, and overhead allocation.
Enter your billable hours, blended rate, realization rate, and cost per attorney hour. The calculator returns the estimated profit margin so you can decide whether a practice area, client, or fee arrangement is actually pulling its weight.
Use this before quoting flat fees, evaluating contingency files, or deciding whether to take on a new client type.
Why use itBuilt for the way law firms actually work
Realization-adjusted math
Accounts for the gap between hours billed and dollars actually collected on the matter.
Loaded cost modeling
Uses fully loaded attorney cost per hour instead of just salary so margin reflects reality.
Overhead allocation built in
Subtracts a share of firm overhead so each matter carries its real share of cost.
Instant results
Get a profit margin percentage the moment you finish entering matter assumptions.
100% free
No paywall, no trial, no upsell, and no limit on how many matters you analyze.
No signup required
Run scenarios anonymously without creating an account or sharing client data.
ProcessHow it works
- 01 Enter hours and rate
Input the billable hours worked on the matter and your blended hourly rate.

Use your fully loaded attorney cost, including salary, benefits, payroll tax, and bonus.
- 04 Allocate overhead
Assign a portion of firm overhead such as rent, software, and admin to the matter.

The tool returns net matter profit as a percentage of collected revenue.

ContextWhy this matters
According to the 2023 Clio Legal Trends Report, the average lawyer bills only about 2.6 hours of an 8 hour workday, and collects on roughly 86% of what gets billed. That gap between hours worked, hours billed, and dollars collected is where matter profitability quietly disappears.
Firms that track profitability at the matter level can identify which clients, practice areas, and fee structures actually fund the firm and which are subsidized by everything else. Without this view, partners often discover at year end that a high revenue practice was running at break even once realization and overhead were applied.
This is especially important for solo and small firms considering flat fee work, contingency files, or large discounts. A 70% realization rate combined with heavy overhead can quietly turn a profitable looking engagement into a loss.
Q&AFrequently asked
- It is a tool that estimates the net profit margin on a single legal matter after accounting for realization rate, attorney cost, and allocated overhead. It helps firms decide which matters, clients, and fee structures are actually profitable.
- Yes. It is completely free, requires no signup, and has no usage limits. You can run as many scenarios as you want.
- It is designed for solo attorneys, small firm partners, practice managers, and law firm CFOs who need to evaluate matter level economics. It is also useful for associates pricing flat fee work.
- Realization rate is the percentage of billed time that the firm actually collects from the client. Industry benchmarks typically range from 80% to 90%, with write-downs and unpaid invoices accounting for the rest.
- A billing rate calculator tells you what to charge. A profitability calculator tells you what you actually keep after collection losses, attorney cost, and overhead are subtracted.
- Use it before quoting a flat fee, accepting a contingency matter, evaluating a new practice area, or doing year end reviews of which client types are worth keeping.
- No. This is a planning and scenario tool. For official financial reporting, trust accounting, and tax work, use your accounting system and consult a CPA familiar with law firm accounting.
- The most common error is using salary alone as attorney cost instead of fully loaded cost. Benefits, payroll tax, bonus, and non-billable time can easily add 30 to 50% on top of base salary.
